7 guate signal to such pedestrian or approaching driver due to light signal from a'common source through this control or hood which projection is preferably in the form of a colored ray, as green or green and red.

Referring to the drawings: p V Fig. lis a fragmentary view of a motor 7 r vehicle 'embodyingfeatures of the in n I as adapted thereto in theform of an attachment to the regular headlights for such vehicle; I

Fig. 2 is a front view of'the headlight hood 2a in demountedposition;

, Fig. 3 is a partial section on the line III-III, Fig.1 g

Fig. a is a side elevation of the hood or attachment mounted with one of the lights of 55 Big. 1; and

Fig. 5 is a section on the line VV, Fig. 3. Motor vehicle 1 is shown ashaving drivers station 2, and headlights 3, 1. These headlights are provided with. housing having I 35 therein parabolic reflector or projector 5. In

the central portion of such projector 5 is socket 6 for incandescent electric bulb 7 having filament 8. These lamps 3, 4, are shown of the drum type having forward rim 9 holding in position lens 10. Mountings l1 position the headlights as to the frame of the vehicle'l and leads '12, 13, supply electric cur- 'rent for controlling the illumination of the filament Sin the bulb 7. I

' I on theinner side of the housing just back of the forward rim 9, threaded portions, as

nuts 14, may be soldered into position or otherwise anchored, to permit flat head screws entering flush with U-shaped band 16 to coact in fixedly mounting such band as a foundationon this headlight housing. 'With suchas a foundation, bolts 17 serve to clamp supplemental U-portion 18 upon this base ELI-portion 16 to clampfiexible portion, as

leather, for joint hinge 19 of forward projecting hood :portion 20 having eyes 21 engagedby the lower pair ofbolts17 as mount ing theclamp U-memberl8. There is, thus a. pivotal connection for. this. forwardly extending'hood member 20.

This hood member 20 is maintained inadjusted position by brackets 22'l1aving. fixed connection 23 "with the hood. and extending through eyes 24 and secured by nuts 25 on each side'of said eyes 2 1.. This, hood 20 is,

accordingly," adjustable on its pivot mountings21 as. permitted by the flexible portion 19. :This leather 1 .portion vl9 serves asv a weather sheddinghinge. Adjustment of the angleof; this hood :20 may be, effected with delicacy. and. maintained rigidly against vibration. o I

.The hood 20, as projecting forwardly from theaheadlight, is providedwithlower side portions26 extending from dropportions 27 as cheeks for forward lip '28. 'From this portion 28; isa slight rise 29;.for a shortdistance rearavardly toseat 30 in which ismounted lens 3lire jained;bysplit-ring 32. The in- 12i 1t133, of thi hood 20 is of lig treflec ing In practice it is desirablethat this hood control or lamp ay proj ection from the bulb in the headlight be so that direct clear rays may not glare to blind or confuse an approaching pedestrian or driver. The adjustment as permitted by the brackets 22 permits an accurate control for the maximum height line for intense ray projection. The reflector 5 in combination with the lens 10 and reflector interior 33 of the hood 20 are factors in efficient distribution andprojection of the rays in the limited field. No direct rays from the bulb are sent out to confuse trafiic. The bulls eye lens 31, which may he, say green, red, yellow, or a selected color, is an eflicient signal of the approaching vehicle and its location.

The lower edge 26 of the hood 20 may on the inner side thereof as approaching the N ing a forward opening, a lens in the opening, r

a light bulb in' the housing for directing hinge mounting portion 21, have cutout portion 35 so that the light dispersing interior 33 of the hood 20 may be effective in lighting up license plate 36 as carried by the vehicle 1.

What is claimed and it is desired to secure by United States Letters Patent is 1. A headlight housing, a light bulb therein, and lenses for rays from said bulb eclipsed by one lens as to the field of the other, there being a relatively adjustable, forwardly extending hood for mounting one of said lenses approximately parallel to the other and in laterally offset position from a line forward centrally of the other lens and the bulb.

2. A demountable adjustable semi-cylindri- V cal hood for a headlight complete in itself comprising a detachable pivotal mounting, a locking clamp therefor,'and a distensible folded continuous upper section from the mounting. j 8. A demountable adjustable semicylindrical hood for a headlight comprising a detachable pivotal mounting, a locking clamp therefor, a distensible folded continuous upper portion, and adjusting brackets effective for shifting the hood as to said upper portion.

4. headlight comprising a' housing havlight rays through the lens, and a semi-cylindrical hood extending forwardly from said lens and having its axis approximate.

the line from the bulb through the central portion of the lens for projecting forwardly of the housing, said hood forwardly terminating in a drop portion including an addigional lens approximately parallel to the other ens;

in, a first-lens in the housing, an open'bottom adjustable hood extending forwardly from the housing, a second lens in the forward portion of the hood laterally offset from a line forward centrally of the housing carried lens and bulb and approximately parallel to the other lens. v

In witness whereof I affix my signature.
